50 Amp RV Box Adapter

[worknomore]

Does anyone have experience with the box adapters that CW sells (about $60, I believe). I'm talking about the 50 amp adapter box with (2) 30 amp pigtails that plug into the park's (2) 30 amp or 30/20 amp receptacles. The box also has a 50 amp for the RV to plug into.

I read the buyers responses on the CW site - some good, some bad. I've also seen a couple of rigs using them, but didn't have a chance to talk to them. I'm using a 50 -> 30 amp dogbone right now, but have gone thru 2 of them in the last 8 months (corrosion, etc.) that have caused CB's to pop in the rig (especially the micro/convection oven).

It seems like the ideal solution to get 50 amps all the time, if it works as designed...
